Tetakirere pūrerehua rerekē torue whakamahia whānuitia ana i roto i ngā horopaki ahumahi me ngā whakaritenga tino pakari mō te mahi hiri me te urutau ki ngā āhuatanga mahi nā runga i ōna painga matua pēnei i te hiri kore turuturu, te ātete ki te pēhanga me te pāmahana teitei, te ātete rere iti, te ātete kakahu me te ātete ki te waikura. Ko ngā horopaki e whai ake nei e whakamahia whānuitia ana:

1. Te umanga hiko

Ko te nuinga o te wā ka whakamahia i roto i ngā pūnaha poihā (wai whāngai, paipa mamaoa), ngā pūnaha whakakorenga me te whakakorenga hau para, me ngā pūnaha wai rere o ngā tipu hiko wera me ngā teihana hiko karihi. Hei tauira, me tu atu ngā paipa mamaoa matua o ngā poihā me ngā paipa mamaoa kua whakamahanahia anō i ngā pāmahana teitei (tae atu ki te 500℃) me ngā pēhanga teitei (neke atu i te 10MPa). Ko te hanganga hiri mārō whakarewa o te porowhita eccentric torutakirere pūrerehuakāore e taea te turuturu, ka karo i te moumou pūngao me ngā tūponotanga haumaru e puta mai ana i te turuturu o te mamaoa. I roto i te pūnaha whakakorenga whanariki, ka taea e ia te tu atu i te mimiti o ngā mea waikura pēnei i te paru kōhatu.

2. Ahumahi matū hinu

E tika ana mō ngā paipa kawe hinu mata, ngā hua hinu kua whakapaia, me ngā rauemi mata matū (pēnei i ngā otinga waikawa me te kawakore, ngā whakarewa waro), tae atu ki te whakahaere tomokanga me te putanga o ngā oko tauhohenga me ngā pourewa. Hei tauira, i roto i ngā ara iahiko waenga o ngā paipa hinu mata tawhiti me ngā tipu whakapai me te matū, ka taea e te takirere pūrerehua hiko-toru-whakawhiti te urutau ki ngā pāpāho tino waikura me te matotoru teitei. I taua wā, ka tere te whakatuwhera me te kati, ka taea te tapahi tere, te whakahaere rānei i te rere o te reo kia mau tonu ai te whakaputanga.

3. Ahumahi maimoatanga wai

Tae atu ki ngā pūnaha wai, ngā whare tukatuka para me ngā pūnaha maimoatanga para ahumahi. E whakamahia ana mō te kawe wai ma, te tango para, te whakamahi anō i te wai kua whakahokia mai me ētahi atu hononga, inā koa i roto i ngā paipa para kei roto ngā totoka me ngā poke kua whakatārewatia. He iti te ātete o tōna pereti takirere kua whakangawaritia ki te rere, kāore e ngāwari ki te ārai, ā, ka taea e tōna ātete ki te pakaru te ātete ki te mimiti o ngā matūriki i roto i te para. Ka taea e tōna mahi hiri te ārai i te turuturu o te para me te whakaputa i te parahanga tuarua.

4. Ahumahi whakarewa

E whakamahia ana ki ngā paipa hau oumu pupuhi, ngā paipa mamaoa whakawhiti, ngā pūnaha tohanga wai whakamatao, ngā paipa tango puehu, me ētahi atu. Kei roto i te hau oumu pupuhi te puehu me ngā wāhanga waikura, ā, ka tino rerekē te pāmahana. Ka taea e te hiri mārō me te hanganga ātete-kakahu o te takirere pūrerehua takitoru-āhua-toru Hainamana te mahi pumau mō te wā roa. I taua wā, ka taea e tana mahi whakaweto tere te aro atu ki ngā āhuatanga ohorere i roto i te hanga whakarewa.

5. Te hangarau ā-rohe

Ko te nuinga o te wā ka whakamahia i roto i ngā paipa whakamahana pokapū o ngā tāone (te wai wera pāmahana teitei, te mamaoa) me ngā paipa tuku me te tohatoha hau māori. Me tu atu ngā paipa whakamahana ki ngā pāmahana me ngā pēhanga teitei, ā, he tino teitei ngā whakaritenga hiri mō ngā paipa hau māori (hei ārai i ngā mōrearea turuturu me te pahūtanga). Ka taea e ngā takirere pūrerehua ahumahi te whakataurite i te pono o te hiri me te ngāwari o te mahi, ā, he pai mō ngā whakaritenga mahi roa o ngā whatunga paipa tāone.
